Question:

I recently upgraded to virtualbox 5.2.4 and vagrant 2.0.1 because of this issue. Since then, I haven't been able to run any of my vagrant boxes (some ubuntu, some centos). I get the following error when running vagrant up:

There was an error while executing VBoxManage, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.

When I just run vboxmanage without --type headless, I get a popup saying to run /sbin/vboxconfig.

RTR3InitEx failed with rc=-1912 (rc=-1912)

The VirtualBox kernel modules do not match this version of VirtualBox. The installation of VirtualBox was apparently not successful. Executing

'/sbin/vboxconfig'

may correct this. Make sure that you do not mix the OSE version and the PUEL version of VirtualBox.

where: supR3HardenedMainInitRuntime what: 4 VERR_VM_DRIVER_VERSION_MISMATCH (-1912) - The installed support driver doesn't match the version of the user.

No luck even after running sudo /sbin/vboxconfig multiple times.

I've tried reinstalling virtualbox and the extension pack multiple times and reinstalling linux-headers and dkms as seen in answers to questions similar to this one, but nothing has worked. Any ideas?

Edit: Just tried it out on 5.1, but it's the same error, 5.0 just hangs my computer

Solution:1

OK. Figured out the problem here. My kernel modules hadn't been deleted from the previous install of virtualbox when I uninstalled. So when I ran modinfo vboxdrv, it said I was using the kernel drivers for 5.0.4.

I deleted everything in the path to the filename given in the modinfo output and rebooted. Installing virtualbox and starting vms worked after that.

Solution:2

Try running it with root permissions through sudo:

sudo /sbin/vboxconfig

It worked on my case.

Solution:3

Just had an issue where a system update clobbered my Virtual XP, giving the "rc=-1912" error, the suggestion of reinstalling, etc. What I found worked was sudo apt-get update sudo apt-get upgrade Seemingly overly simple but worked here!
